AUDIO RESTORATION

During our audio restoration work, we offer a comprehensive range of services to ensure the highest quality restoration and enhancement of your audio recordings. Our services include:

Noise Reduction is the process of eliminating or reducing unwanted noise or disturbances that can be present in audio recordings. Noise can be introduced during the recording process due to various factors such as already present background noise, electrical interference, microphone handling noise, tape hiss, or poor input signal quality. The noise reduction techniques commonly used by us:

• DeBird
• DeBreath
• DeClick
• DeClip
• DeCrackle
• DeEss
• DeHum
• DePlosive
• DeReverb
• DeRustle
• DeWind
• Dialog Extract
• Wow and Flutter Removal

Spectral Recovery aims to restore frequencies above 4000 Hz that may have been lost during streaming or conference calls. This is a common challenge due to the limitations of the audio codecs and bandwidth constraints typically associated with these communication platforms. It is not always possible to completely recover the lost frequencies above 4 kHz.

Volume Normalization is done to ensure that the restored audio material matches the desired loudness standards and maintains a consistent volume level. Depending on the speciffic requirements of the audio material we offer:

• Loudness Normalization
• Peak Normalization
• RMS Normalization
• Normalization with Dynamic Range Compression

AUDIO EDITING

At equisonus we offer audio editing services for both single track and multi-track audio recordings. Our audio editing services include:

Edit or remove content from your audio

This can involve various modifications such as removing silence, specific words, filter words like "ah" and "um", correcting mistakes, or even trimming and removing undesired parts of the audio material.

Audio Format and Sample Rate Conversion

We provide audio format and sample rate conversion services to ensure compatibility and optimal playback of your audio material across various platforms and devices. Audio format conversion involves converting audio files from one format to another (like WAV, AIFF, FLAC, MP3, AAC), while sample rate conversion involves changing the sample rate of an audio file. Utilizing industry-standard software and our expertise the quality of your audio files is preserved throughout the conversion process.

Center Extract

We can treat your audio material to preserve or remove the center channel of a stereo or surround sound recording. The center channel typically contains the main elements of the audio, such as vocals, lead instruments, and dialogue in the case of video content. We have the capability to preserve the center channel, maintaining focus on the main audio elements. Additionally, we can remove the center channel to isolate specific elements from the mix as needed.

Dialogue Contour

With dialogue-specific pitch correction, we have the ability to modify the intonation or tune the inflection of individual words within a phrase that may not align with the overall dialogue. This allows us to ensure a consistent and cohesive vocal performance, correcting any discrepancies in pitch or tonality that may arise within the dialogue recording.

Unmixing

Utilizing this technique we can separate vocals from instruments in an audio recording. This treatment is commonly employed in situations where there is a need to remix or modify the individual elements of a mixed recording. However, it is important to note that extracting the vocal track from a mixed audio file may not always yield perfect results. While the vocals can be isolated to a certain extent, there may still be some remaining "leaked" sounds from other instruments present. To address this, we'll manually remove the residual artifacts from other instruments using professional audio editing software such as iZotope RX Advanced and Steinberg WaveLab Pro.
